Abstract
Chickpea (Cicer arietinum L.) is one of the most important pulse legumes in many
parts of the world. India is largest producer of chickpea in the world, sharing 65 and 70 % of the
total global area and production, respectively. However, productivity of chickpea in India is quite
low. Out of several factors responsible for low productivity losses caused due to weeds is one of the
most important which averaged out to be 30-54 %. Considering these facts an experiment was
carried out at Research Farm of Banda University of Agriculture and Technology, Banda during
Rabi season of 2019-20. The research was carried out to find out the cost-effective herbicide for
controlling weeds and to fine tune the dose of herbicide with the impact of weed management
practices on growth and yield of chickpea. The field experiment was laid out in Randomized
Complete Block Design (RCBD) with three replications. The treatment contains: T1-Weedy Check,
T2 -Weed Free, T3 -Pendimethalin 1000g PE fb 1 HW, T4 -Oxyfluorfen 100g PE fb1 HW, T5 -
Imazethapyr 40g PoE, T6 -Quizalofop-ethyl 50g PoE, T7 -Pendimethalin 1000g PE fb Imazethapyr
40g PoE, T8 -Pendimethalin 1000g PE fb Quizalofop-ethyl 50g PoE, T9 -Oxyfluorfen100gPE fb
Imazethapyr 40g PoE and T10 -Oxyfluorfen100gPE fb Quizalofop-ethyl 50g PoE.
During investigation major weed flora observed in experimental crop were Cyperus
rotundus (sedge weed), Digera arvensis, Anagalis arvensis, Chenopodium album, Euphorbia
dracunculoides, Chenopodium murale, Eclipta alba, Asphodelus tenuifolius, and Vicia sativa among
broad leaf, and Cynodon dactylon among grassy weeds. Among several category of weeds sedge
weeds in majority followed by broad leaved and grassy weeds. Among herbicidal treatments
Pendimethalin 1000g PE fb Imazethapyr 40g PoE (T7) treatment proved efficient method of weed
management with higher weed control efficiency (%). Considering chickpea yield and economics
Pendimethalin 1000g applied as pre emergence along with 600 l of water and Quizalofop-ethyl 50g
as post emergence (25 DAS) along with 500 l of water found cost effective and profitable option for
weed management in chickpea
